Lifesaving cardiac monitor technology unveiled

16.12.2004

A revolutionary Personal Health Status Monitor for early detection of life threatening cardiac rhythms is just one of the exciting new medical devices set to revolutionise health care on show at the Personalised Health Workshop in Belfast.

In recognition of their expertise in the areas of e-health and sensor technology, researchers at the University of Ulster have been asked by the Information Society Directorate-General for eHealth at the European Commission to organise the 2nd International Workshop on Personal Health Management Systems. The event, Personalised Health: The integration of innovative Sensing, Textile, Information and Communication Technologies, takes place at W5 on December 13, 14 and 15.

University of Ulster scientist Dr Eric McAdams said: “Here in Ireland, heart problems are the worst in Europe, and each year, over 500,000 sudden deaths occur in the US due to cardiac arrhythmias.

“Survival rates of sudden cardiac arrest rise from less than 10% in public, to over 70% if witnessed within an acute care setting.The chances of surviving a life threatening arrhythmia diminish substantially if the heart is not returned to normal rhythm within 4-6 minutes," he said. “Current means for early detection and notification of a severe cardiac arrhythmia is limited by current costly medical instruments found in high intensity acute care settings. “Those patients at risk in lower intensity hospital settings, or in the home have no means for surveillance monitoring of a life threatening event.”

Now, leading US company Welch Allyn, with the help of technology developed by University of spin-out company, Sensor Technology and Devices, have developed a cost effective, easy to use, highly sensitive personal status ECG.

The device’s body-worn sensors wirelessly communicate the health status of the patient to the appropriate centre in the hospital, clinic or home, leaving the patient free to walk about and lead a normal life. The product provides continuous surveillance of the patient and enables the early detection of life threatening cardiac events.

Dermot O’Doherty, Senior Policy Adviser, at the sponsors InterTradeIreland, said: “IntertradeIreland regard this emerging technology as important in creating opportunities to build on research being carried out in the Universities on the island –and in developing the fast-growing, high added value medical devices sector. We are especially excited about the prospects for integration of sensor technologies into textiles – a sector moving rapidly to change its traditional image.

Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.

It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:

The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.

One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
